How can I calculate osmolarity of dextrose?

Answer 1

The solution will closely resemble the ideal equation if it is sufficiently diluted:

#P=cRT#

where T is the absolute temperature (K), R is the universal gas constant (8.314 J/mol-K), c is the concentration (moles per cubic meter), and P is the osmotic pressure (Pa).

Rearranging this expression allows you to calculate the concentration from a measured osmotic pressure (differential pressure across a semi-permeable membrane). You can then convert c to molarity (divide by #10^6 L/m^3#). The result will be very close to the molality if the solvent is water and the solution is dilute, because because 1 L of water has a mass very close to 1 kg.

Answer 2

To calculate the osmolarity of a dextrose solution, use the formula:

Osmolarity (in mOsm/L) = [Number of particles of solute] × [Concentration of solute (in mol/L)]

For dextrose (C6H12O6), it dissociates into one particle in solution. Calculate osmolarity using the above formula based on the concentration of the dextrose solution.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
